When should i get my boiler serviced?

We recommend having your boiler serviced by a professional gas safe engineer at least once a year.

With many boiler warranties you’re actually required to complete a regular service to ensure your boiler is safe. An annual boiler service will meet most insurance policy requirements, though you’ll need to check with your insurance provider to be sure.

Summer is the best time to book your service in. Not only will you be making sure you’re set once the colder weather kicks in, but also summer is the quietest time of the year for gas engineers giving you more flexibility on what time and day they are available.

Keep your warranty intact

All new boilers come with a warranty ranging from 2 years to 10 years, this warranty protects you from any genuine faults with your boiler as the manufacturer will repair the boiler free of charge. To keep this warranty valid manufacturers require the boiler to be serviced which assures that the fault is genuine not due to negligence.

If you do not have a service once in every 12 months then your warranty could be void and if a problem occurs, you’re likely to be liable to pay the full repair costs.

Catch faults in your system early

The majority of the time you won’t know about a problem with your boiler until you’re left with no heating and/or hot water. During a boiler service, your expert gas engineer will be able to identify any underlying problems or potential issues before it’s too late. No matter how small the issue with your boiler, ignoring it could lead to a costly repair bill.

Keep you and your loved ones safe

Gas leaks are rare however extremely dangerous or even fatal. Carbon monoxide poisoning can cause symptoms such as headaches, dizziness, nausea, breathlessness, collapsing and a loss of consciousness. 250 hospitalisations a year are caused by carbon monoxide poisoning between 2001 and 2010 in England & Wales. Therefore, it’s critical that you have your boiler serviced regularly giving you peace of mind that you and your family are safe.

Save money on your energy bills

As your boiler gets older, it inevitably becomes less energy efficient but with regular servicing you can slow down this process. During your servicing, your engineer will carry out all necessary checks to ensure that your boiler is running as efficiently as possible. The more energy efficient your boiler is, the more money you could save over the year. A boiler that is not working to its full potential and isn’t performing efficiently, could cause an unexpected increase in your energy bills.

How Much Does A Boiler Service Cost?

On average it costs around £80 to get your boiler serviced although this can vary from £60 – £100.

You could however take out boiler and central heating cover. This costs more, around £180-£300, but will also cover you for any breakdowns.

If you have a cover policy or insurance for your boiler then check to see if an annual service is included as part of the charge.

What is The Best Boilers for Central Heating?

While there are several boilers on the market from a variety of different brands, finding the best boiler for your home can be a difficult decision. Currently there are three main types of domestic boilers; combi boilers, system boilers and conventional boilers. When it comes to choosing the best type of boiler for your home, there are plenty of different factors to consider including: number of people, type of home, water pressure etc.


Combi-boilers are the most affordable residential boiler for most households. They control both hot water and central heating, and their energy efficiency makes them the unit of choice for environmentally-conscious homeowners. Heating water directly from the mains and whenever a tap is turned on, you can get unlimited hot water whenever you need it. There’s no need for a cylinder or water tank, saving you space in your home and cutting down the installation time.

Combi-boilers don’t require a cold-water tank or a hot water cylinder which helps to save space. That means they’re an ideal option if you live in a flat or a smaller household. Combi-boilers also heat up the water directly from the mains meaning you get unlimited hot water without waiting.

System Boiler

Do you have more than one bathroom in your home? If so a system boiler could be the solution.

Conventional Boiler

Conventional boilers takes up more space than other solutions and are far less efficient with hot water not on demand.

Why Is My Boiler Humming?

If your central heating is making a humming noise, the main culprit is usually your central heating system. The humming noise can also be accompanied with a vibration which again leads to a pump issue. Although the main culprit it is not the only cause of a humming noise

Below, we’ve listed four common problems that can cause a loud humming noise to come from your boiler.

Heating Elements

A humming boiler could mean that your heating elements are not working at their best which includes the following:
  • thermostat
  • central heating pump
  • pressure gauge
  • filling loop

Loose components

The most common cause of a boiler humming is a slight vibration in the casing. If your boiler has recently been serviced or repaired and the humming noise started shortly after then loose components is the most likely cause.

Components to look for are as follows:

Loose brackets
Solution (try tightening the screws with a screwdriver)

Vibration of the unit itself
Solution (get a professional to secure the unit with brackets)

Circulating Pump Set To Wrong Speed

Every central heating system is different to the next, one home may have 10 radiators while another may have 14. One home may have a one layout meanwhile another home has a layout with more piping. Different homes for these reasons and more require a bespoke speed for that particular home.

Luckily boiler manufacturers integrate a variable speed dial which allows you to easily increase and decrease the speed of water circulating your home. Simply located your circulating pump and adjust the setting to the lowest setting to see if the humming stops.

High pressure in the system

Boiler pressure is the balance of water and air within your heating system. In order for your boiler to pump hot water around the pipes in your home the pressure needs to be the correct amount.

High boiler pressure puts unnecessary strain on your heating system and the boiler could break down.

How To Check My Boiler Pressure

On average your boiler pressure should be between 1 and 2 bar however some boilers are different so checking your boiler manual.

To check your boiler pressure, you need to locate the pressure gauge on your boiler. If there is the correct amount of pressure in your system, the needle should be between 1 and 2 bar.

boiler pressure gauge

Most boilers have a pressure gauge similar to the image shown where green is between 1 and 2, this shows the zone of ideal pressure. The red zone which is greater than 2 is then indicated in red highlighting the critical strain on your boiler.

How To Lower Boiler Pressure

If the boiler pressure is above 2 bar or the needle is in the red zone on the pressure gauge then you will need to release some of the pressure bringing it back down to a correct amount. Step one is to turn your water and heating off which should bring the pressure back down.

If the problem continues to occur then to release some of the pressure the easiest method is to bleed a couple of radiators in your home. Simply turn off your heating and with a radiator key or a flathead screwdriver turn the valve and with a towel or bowl catch the water, once the pressure has lowered below the red zone then close the valve.

There are many different noises that your boiler can make, and while some of them can seem worrying at first, most can easily be fixed. If you are unsure about any noise your heating system is making, the safest thing to do is call a professional.
